Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour(R) technician will walk you through all costs using our Straightforward Pricing(R) Guide so there are never any surprise fees.

How often should I service my HVAC system?

It's ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

How often do I need to change my HVAC filter?

Your filter should be changed every one to three months, depending on conditions in your home and your region's climate.

Do you offer purchase financing?

We work built relationships with several lenders to ensure our customers are able to restore comfort in their homes. Ask your technician about your financing options.

What are the advantages of a smart thermostat?

Smart thermostats learn a household's patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.

HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter. In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house. Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.

What is a SEER2 Rating?

The SEER2 (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER2 rating, the more efficiently a unit operates. The SEER2 rating of any given unit can range anywhere from 13 to 21.

“Michael and Austin came out to install a new a/c unit. They did a great job! So professional and just fine young men, knowledgeable and kind. My grandchildren (ages 8, 6, and 5) asked lots of questions and they answered them with such kindness. We have used Joe East since 1984. Never have been dissapointed. Great job. Thank you!”

“Let me tell you about James, your employees. He came to my home 6/4/25. I kinda expected the same service I had been getting in and out with in 30 to 40 minutes. Not with this young man James. I watched him do things that had not been done before. He is a very kind and respectful and GODLY young man. Thank you Joe East, for having hard working men to care for your customers. God Bless.”

“The service agreement I have with Joe East that calls for 2 visits a year is some of the best money I spend each year. The technicians catch a lot of issues before they become a catastrophic problem and are normally able to give me a heads up when it's time to replace a unit before it goes out. I've been a customer for 25 years now.”

“From sales to install, Joe East was great. Guy was able to get me a great estimate and made sure I was taken care of on the weekend and Keaton and Seth did a phenomenal job installing a new unit. They were very professional, personable and, made sure all my questions were answered before leaving.”
